Value Collection 557u2/0 Taper Pin Reamer 2/0 Hss

Product Description

The VALUE COLLECTION 557u2/0 is a 2/0 taper pin reamer designed for hole enlarging, finishing, and shaping operations in precision machining and assembly applications. Manufactured from high speed steel (HSS) with a bright, uncoated finish, this reamer features a spiral flute with left-hand spiral direction and right-hand cutting action. The small end diameter measures 0.1137 inches and the large end diameter measures 0.1462 inches, matching the taper rate of 1:48 standard taper pin geometry. The square shank measures 5/32 inches (0.1563 inches) in diameter and seats securely in a tap wrench or appropriate driver. Overall length is 2-9/16 inches with a flute length of 1-9/16 inches.

This reamer is suited for general-purpose use in machine shops, tool rooms, and maintenance environments where taper pin holes must be opened to size or brought to a clean, accurate finish. Typical applications include fitting taper pins in mechanical assemblies such as shafts, gears, and linkages where a precise, interference-fit hole is required. The 2/0 pin size covers a specific range of small-diameter taper pin work and is commonly used in light-duty mechanical assembly and repair contexts.

Installation Notes

This tool is typically used by machinists and maintenance technicians in manual or machine-assisted reaming operations. Power down and secure any workpiece or assembly before reaming. Use cutting fluid appropriate to the workpiece material to extend tool life and achieve a cleaner finish. Apply steady, even pressure and avoid excessive force that can cause chatter or bell-mouthing at the hole entrance.
